"Expanding trade in a way that is freer and fairer for all Americans requires that other economies avoid unfair currency practices, and we will continue to monitor this carefully", he said.
Trump has said some USA trading partners, particularly China, manipulated their currency, but has since backed off that claim and acknowledged that China had not weakened the yuan to make its exports cheaper.
While Trump and Chinese President Xi Jinping last week agreed to 100-day trade talks, United States business leaders in China have expressed concern about a lack of progress in gaining further access to the Chinese market despite years of negotiations.
Trump has softened his rhetoric against China's trade practices as Beijing has intervened in foreign exchange markets to prop up the value of its yuan, and as he looks to China for help dealing with rising tension on the Korean peninsula.
Trump's about-face was notable because of how forceful he was in his insistence as recently as this month that China was a currency manipulator.
Trump said during the campaign that he would label China a currency manipulator on day one, leading to fears of a potential trade war.
"While China now meets only one of the three criteria for currency manipulation listed in the report, the text makes clear that China's large bilateral trade surplus with the United States is by itself enough to warrant careful scrutiny of China's trade and currency practices", Prasad said. All five of these countries were also on the list in the previous report. The countries - China, Japan, Germany, South Korea, Taiwan and Switzerland - were the same six named in the last currency report issued by the Obama administration in October.

In response to Le Pen's protectionist views, Macron invoked his hometown of Somme, which was a major battlefield in World War One. She insisted she would not do that immediately if elected, but first hold negotiations and a referendum.
U.S. Treasury Department on Friday declared that no major trading partner of the U.S., including China, met the standard of manipulating its currency, while six economies were listed on its Monitoring List as their foreign exchange polices bear close monitoring.
"An essential component of this Administrations strategy is to ensure that American workers and companies face a level playing field when competing internationally", said Treasury Secretary Steven Mnuchin.
The Treasury said it "will be scrutinizing China's trade and currency policies very closely".
"China now has an extremely large and persistent bilateral trade surplus with the United States, which underscores the need for further opening of the Chinese economy to American goods and services", as well as quicker reforms to boost household consumption, according to the Treasury report.
The report also criticized Japan for failing to do more to stimulate domestic demand and thereby increase sales of USA and other foreign goods.
This would include more "flexible" government spending policies, and continued reforms to boost the labor market and increase productivity of the Japanese economy.
